1. SQLite：
SQLite 是一个提供关系数据库管理系统 (RDBMS) 的软件库。它由 D. Richard Hipp 于 2000 年 8 月设计。SQLite 的设计目标是允许程序在不安装数据库管理系统 (DBMS) 或不需要数据库管理员的情况下运行。
2. 卡桑德拉：
Cassandra 是一个免费、开源、分布式、广泛的列存储、NoSQL 数据库管理系统。它由 Apache 软件基金会开发，最初于 2008 年 7 月发布。Cassandra 旨在处理跨多个商用服务器的大量数据，提供高可用性且无单点故障。 SQLite 和 Cassandra 的区别：
| S.No. | SQLITE | CASSANDRA |
|---|---|---|
| 1. | It was developed By D. Richard Hipp in August 2000. | It was developed by Apache Software foundation and released in July 2008. |
| 2. | SQLite is developed only in C language. | Cassandra is also developed only in C language. |
| 3. | It is widely used in-process RDBMS. | It is wide-column store based on ideas of BigTable and DynamoDB. |
| 4. | The primary database model for SQLite is RDBMS. | The primary database model for Cassandra is Wide Column Store. |
| 5. | SQLite does not require a server to run. Hence, it is serverless. | Server operating systems for Cassandra are BSD, Linux, OS X and Windows. |
| 6. | It supports secondary indexing. | It supports secondary indexing but in a restricted way, i.e., only equality queries, not always the best performing solution. |
| 7. | SQLite provides ACID transactions. | Cassandra does not provide ACID transactions. |
| 8. | It does not support any partitioning methods. | In Cassandra, partitioning can be done using sharding. |
| 9. | It does not support any replication methods. | It support only one replication methods – Selectable Replication Factor. |
| 10. | SQLite provides the concept of Referential Integrity and has Foreign Keys. | Cassandra does not provide the concept of Referential Integrity. Hence, no Foreign Keys. |
| 11. | It supports in-memory capabilities. | It does not support in-memory capabilities. |
